Class OpenMBeanInfoSupport
- All Implemented Interfaces:
Serializable,Cloneable,DescriptorRead,OpenMBeanInfo
OpenMBeanInfoSupport class describes the management
information of an open MBean: it is a subclass of MBeanInfo, and it implements the OpenMBeanInfo interface. Note that an open MBean is
recognized as such if its getMBeanInfo() method returns an
instance of a class which implements the OpenMBeanInfo interface,
typically OpenMBeanInfoSupport.- Since:

OpenMBeanInfoSupport
public OpenMBeanInfoSupport(String className, String description, OpenMBeanAttributeInfo[] openAttributes, OpenMBeanConstructorInfo[] openConstructors, OpenMBeanOperationInfo[] openOperations, MBeanNotificationInfo[] notifications) Constructs an
OpenMBeanInfoSupportinstance, which describes a class of open MBeans with the specifiedclassName,description,openAttributes,openConstructors,openOperationsandnotifications.The
openAttributes,openConstructors,openOperationsandnotificationsarray parameters are internally copied, so that subsequent changes to the arrays referenced by these parameters have no effect on this instance.- Parameters:
className- The fully qualified Java class name of the open MBean described by thisOpenMBeanInfoSupportinstance.description- A human readable description of the open MBean described by thisOpenMBeanInfoSupportinstance.openAttributes- The list of exposed attributes of the described open MBean; Must be an array of instances of a subclass ofMBeanAttributeInfo, typicallyOpenMBeanAttributeInfoSupport.openConstructors- The list of exposed public constructors of the described open MBean; Must be an array of instances of a subclass ofMBeanConstructorInfo, typicallyOpenMBeanConstructorInfoSupport.openOperations- The list of exposed operations of the described open MBean. Must be an array of instances of a subclass ofMBeanOperationInfo, typicallyOpenMBeanOperationInfoSupport.notifications- The list of notifications emitted by the described open MBean.- Throws:
ArrayStoreException- IfopenAttributes,openConstructorsoropenOperationsis not an array of instances of a subclass ofMBeanAttributeInfo,MBeanConstructorInfoorMBeanOperationInforespectively.

OpenMBeanInfoSupport
public OpenMBeanInfoSupport(String className, String description, OpenMBeanAttributeInfo[] openAttributes, OpenMBeanConstructorInfo[] openConstructors, OpenMBeanOperationInfo[] openOperations, MBeanNotificationInfo[] notifications, Descriptor descriptor) Constructs an
OpenMBeanInfoSupportinstance, which describes a class of open MBeans with the specifiedclassName,description,openAttributes,openConstructors,openOperations,notifications, anddescriptor.The
openAttributes,openConstructors,openOperationsandnotificationsarray parameters are internally copied, so that subsequent changes to the arrays referenced by these parameters have no effect on this instance.- Parameters:
className- The fully qualified Java class name of the open MBean described by thisOpenMBeanInfoSupportinstance.description- A human readable description of the open MBean described by thisOpenMBeanInfoSupportinstance.openAttributes- The list of exposed attributes of the described open MBean; Must be an array of instances of a subclass ofMBeanAttributeInfo, typicallyOpenMBeanAttributeInfoSupport.openConstructors- The list of exposed public constructors of the described open MBean; Must be an array of instances of a subclass ofMBeanConstructorInfo, typicallyOpenMBeanConstructorInfoSupport.openOperations- The list of exposed operations of the described open MBean. Must be an array of instances of a subclass ofMBeanOperationInfo, typicallyOpenMBeanOperationInfoSupport.notifications- The list of notifications emitted by the described open MBean.descriptor- The descriptor for the MBean. This may be null which is equivalent to an empty descriptor.- Throws:
ArrayStoreException- IfopenAttributes,openConstructorsoropenOperationsis not an array of instances of a subclass ofMBeanAttributeInfo,MBeanConstructorInfoorMBeanOperationInforespectively.- Since:

Method Details
-
equals
Compares the specified
objparameter with thisOpenMBeanInfoSupportinstance for equality.Returns
trueif and only if all of the following statements are true:objis non null,objalso implements theOpenMBeanInfointerface,- their class names are equal
- their infos on attributes, constructors, operations and notifications are equal
equalsmethod works properly forobjparameters which are different implementations of theOpenMBeanInfointerface.- Specified by:
equalsin interfaceOpenMBeanInfo- Overrides:
equalsin classMBeanInfo- Parameters:
obj- the object to be compared for equality with thisOpenMBeanInfoSupportinstance;- Returns:
trueif the specified object is equal to thisOpenMBeanInfoSupportinstance.- See Also:
-
hashCode
public int hashCode()Returns the hash code value for this
OpenMBeanInfoSupportinstance.The hash code of an
OpenMBeanInfoSupportinstance is the sum of the hash codes of all elements of information used inequalscomparisons (ie: its class name, and its infos on attributes, constructors, operations and notifications, where the hashCode of each of these arrays is calculated by a call tonew java.util.HashSet(java.util.Arrays.asList(this.getSignature)).hashCode()).This ensures that
t1.equals(t2)implies thatt1.hashCode()==t2.hashCode()for any twoOpenMBeanInfoSupportinstancest1andt2, as required by the general contract of the methodObject.hashCode().However, note that another instance of a class implementing the
OpenMBeanInfointerface may be equal to thisOpenMBeanInfoSupportinstance as defined byequals(java.lang.Object), but may have a different hash code if it is calculated differently.As
OpenMBeanInfoSupportinstances are immutable, the hash code for this instance is calculated once, on the first call tohashCode, and then the same value is returned for subsequent calls.- Specified by:
hashCodein interfaceOpenMBeanInfo- Overrides:
hashCodein classObject- Returns:
- the hash code value for this
OpenMBeanInfoSupportinstance - See Also:
-
toString
Returns a string representation of this
OpenMBeanInfoSupportinstance.The string representation consists of the name of this class (ie
javax.management.openmbean.OpenMBeanInfoSupport), the MBean class name, the string representation of infos on attributes, constructors, operations and notifications of the described MBean and the string representation of the descriptor.As
OpenMBeanInfoSupportinstances are immutable, the string representation for this instance is calculated once, on the first call totoString, and then the same value is returned for subsequent calls.- Specified by:
toStringin interfaceOpenMBeanInfo- Overrides:
toStringin classObject- Returns:
- a string representation of this
OpenMBeanInfoSupportinstance
